Unfortunately, this will not find Overdrive Advantage titles. These require you to be logged into your library account to search, as they are only available to specific libraries within a larger consortium. (ed: it looks like it finds Advantage titles if they're available at all the libraries but some have additional copies; but doesn't find them if they only available at all from a select list of libraries within the group)

This plugin would have been great for keeping a "lookout" list of books I'm interested in that aren't yet available at my library(s)--add an empty book record to calibre and then periodically search on that list to see if any have been added. Unfortunately, the ones I would be interested in looking for also tend to be the Advantage titles.
